对尤溪县境内公路沿线低立地级第一重山不同造林更新模式水源涵养功能进行定位观测,结果表明:不同造林更新模式均能改善公早稻沿线第一重山的水源涵养能力,其中以杉松混交林和马尾松人工林的水源涵养能力为最强,林分总持水量分虽达2206.2t/hm22202.8t./hm2,分别比荒山坡增加318.2和315.4。
The water conservation function of different afforestation and reforestation models of the first heavy mountain in low landform along the highway in Youxi County was observed and observed. The results showed that different afforestation models could improve the water conservation capacity of the first heavy mountain along the highway, The water conservation ability of forest and Pinus massoniana plantation was the strongest, while the total stand water content reached 2206.2t / hm22202.8t. / Hm2, which increased by 318.2 and 315.4 respectively than the barren hillside.
